Abstract

A block tread tyre comprises a tread part, which in its centre part is provided with a peripheral series of blocks divided by two broad peripheral main grooves and axial grooves running between these, the tread part on its tread surface being provided with a plurality of first channels, which are narrower than the peripheral grooves and the axial grooves, the axial grooves being shallower than the peripheral groove, each of the axial grooves being provided on its bottom surface with a second channel, which is 0.2-1.1 mm wide, and the second channel extending along the centre line of the axial groove and the ends thereof being closed at the bottom, so that its length is not less than 0.7 times and less than 1.0 times the length of the axial groove, the depth of the axial groove is 0.2-0.5 times the depth of the peripheral grooves, the depth of the second channel is 0.2-0.5 times the depth of the peripheral grooves, and the sum of the depth of the axial groove and the depth of the second channel does not exceed 0.7 times the depth of the peripheral grooves.
